Class
    Foam::functionObjects::DESModelRegions
 
Group
    grpFieldFunctionObjects
 
Description
    Computes an indicator field for detached eddy simulation (DES) turbulence
    calculations, where the values of the indicator mean:
 
    \verbatim
      0 = Reynolds-averaged Navier-Stokes (RAS) regions
      1 = Large eddy simulation (LES) regions
    \endverbatim
 
    Operands:
    \table
      Operand         | Type              | Location
      input           | -                 | -
      output file     | dat               | postProcessing/<FO>/<time>/file
      output field    | volScalarField    | <time>/outputField
    \endtable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    DESModelRegionsFO
    {
        // Mandatory entries
        type        DESModelRegions;
        libs        (fieldFunctionObjects);
 
        // Optional entries
        result      <word>;  // DESField;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: DESModelRegions         | word |  yes  | -
      libs         | Library name: fieldFunctionObjects | word |  yes  | -
      result       | Name of DES indicator field        | word |  no   | <FO>
    \endtable
 
    The inherited entries are elaborated in:
      - \link functionObject.H \endlink
      - \link writeFile.H \endlink
 
Note
    \c DESModelRegions function object can only be executed for DES simulations.
